The present disclosure relates to a braid for treating an aneurysm. The braid can include a first radially expandable segment operable to move from a collapsed state within a microcatheter to a deployed state distal of the microcatheter. The first radially expandable segment can be capable of radially expanding to form an outer occlusive sack in the aneurysm in the deployed state. The braid can also include a second radially expandable segment operable to move from the collapsed state within the microcatheter to the deployed state distal of the microcatheter, wherein the second radially expandable segment is capable of radially expanding inside the outer occlusive sack to form an inner occlusive sack in the outer occlusive sack in the deployed state.本揭露係關於一種用於治療一動脈瘤的編織物。該編織物可包括一第一徑向可膨脹區段，其可操作以從一微導管內的一塌縮狀態移動至該微導管遠側的一展開狀態。該第一徑向可膨脹區段能夠徑向膨脹，以在該展開狀態下在該動脈瘤中形成一外部閉塞囊。該編織物亦可包括一第二徑向可膨脹區段，其可操作以從該微導管內的該塌縮狀態移動至該微導管遠側的該展開狀態，其中該第二徑向可膨脹區段能夠在該外部閉塞囊內徑向膨脹，以在該展開狀態下在該外部閉塞囊中形成一內部閉塞囊。
